The girl was one of three patients in critical condition at San Francisco General Hospital. Officials would not release her age or identity.
Two others were killed immediately in the crash, and more than 70 were injured.
San Francisco Chronicle has more:
The hospital treated more than 60 people from the crash, releasing most. Two adults remain in critical and four others, including another minor girl, remain hospitalized with various injuries.
The most critical injuries include spinal cord, abdominal and internal bleeding.
The NTSB continues to investigate the crash, which occurred during landing when the tail of the plane made contact with a seawall prior to the runway, causing the plane to tumble and catch on fire.
